I am having the same issues as others.  My Pandora app worked fine for 3 weeks on my new Samsung Q50R QLED tv that I just bought 4 weeks ago.  Then all of a sudden one week ago it will no longer play.  It displays the bars that move with a song at the top of the screen, but the song is not playing and the timer at the bottom shows all zero's.  I have tried every single suggestion offered on this discussion thread and NONE have worked.  I do not have the IPv6 option available on my tv.  And yes I have deleted the app and reinstalled, rebooted my router, etc etc.  Pandora works on all my other devices in my home just fine.  I am a heavy user of Pandora and do not care for the other music apps.  This appears to be a Pandora issue and has been going on for two years according to this thread!!!  Why can't you fix this?  Please advise! ...
